Its place usually represents the degree of accuracy of the number. The only exception (that I can think of) is when the last digit is 0 and it is there only for conventional reasons - for example money values being given to 2 digits after the decimal point. Wiki User

The last digit indicates the degree of significance.

### If you add several numbers how many significant figures can the sum have?

The number whose farthest right significant digit determines it. Whatever place that digit is in is the last significant digit in the sum. For example: 433 + 150 + 3.67 + 8000 = 8586.67, but in sig figs this is only 9000, as the thousands digit is the lowest digit that can be represented.

As trailing zeros after a decimal point make no difference to the value of a number and are not normally written but 0.08240 does have one written, the trailing zero must be significant. Counting form the first non-zero digit to the last significant digit (inclusive) there are 4 sig fig.
